To all whom it may concern: finger. The handle as shown is com d Be it known that I, CHARLES A.

The intermediate insuknob, casing or other part of the apparatus lating section 10 is only necessary when the as to affect the tuning of the apparatus by sections 8 and 90f wood are used.

The pivot 16 can be com ressed slight- 1y, by pushing on the handle, if necessary, to bring the pinion 15 into frictional engage ment with the dial.

The implement can be used for adjusting several dials of the same set, or the dials of several sets, inasmuch as the one im lement can be used for any number of dials, and when not in use can be placed away so as not to incumber the panel, dials or other arts of the outfit. The implement can also lie used for turning dials of different diameters.

Havin thus described the invention, what is claime as new 1s:--

1. An implement for adjusting a dial com rising a handle normally removed from the ial and adapted to be manipulated and rotatedby hand, means on the handle to frictionally engage the dial for turning the dial by the rotation of the handle, and means on the handle for pivotal connection with a portion beyond the edge of the dial, the lastnamed means being yieldable so that the first named means can be moved with the handle to en age the dial.

2. An imp ement for adjusting a dial comprising a handle normally removed from the dial and adapted to be manipulated and rotated by hand, a friction pinion carried by the handle to frictionally engage the dia, and a pivot portion carried by the handle beyond said friction pinion to pivotally engage asurface beyond the edge of the dial, said plvot portion being yieldable so that the pinion can be moved with the handle to engage the dial.

3. An implement for adjusting a dial comprising a handle, and a ti member on one end portion of the handle having a friction pinion to frictionally engage the dial, and having a yieldable pivot projecting beyond said pinion to pivotally engage a surface beyond the edge of the dial.

4. A dial adjuster comprising a rotary handle and a tip member of soft rubber on--- one end of the handle, said member having a friction pinion to overlap and engage the dial, and having a pivot projecting beyond said pinion to pivotally engage the panel.

In testimony whereof I have signed my name to this specification.
